Hello,
I'm using a few TLC59283 ICs to drive seven segment displays, HDSP-521G, Vf = 2.0V. For highest efficiency and least heating of the TLC59283, what would be the best voltage to supply the LED displays with? 3.3V or 5.0V? I think I only need about 20mA per segment.
Also, is there a way to use one potentiometer to control the current on threeTLC59283 ICs? Client wants a common brightness control for all the digits.
Thank you,
Derek
